init: Retain traditional restart behavior for critical and oneshot services.

Adds an SVC_RESTART state that's used for an explicit "restart" of a
running service.  This retains the traditional restart behavior for
critical and oneshot services (previously altered by 7e36edd8), whereby
these services are "simply restarted" instead of counting as a crash (for a
critical serivce) or going into the disabled state (for a oneshot service).
